Disclosed is an edge wrapping method for a composite board, the top board of the composite board surrounds the bottom board of the composite board, a part or all of the side of the top board is disposed with a connecting portion extending beyond the bottom board and extending outwardly; the adjacent portion of the connecting portion and the bottom board are heated, and then the connecting portion is folded toward the inner side of the composite board and the connecting portion is welded to the side of the bottom board. The connecting portion and the bottom board are heated, and the root portion of the connecting portion near one end of the bottom board and the position of the bottom board close to the connecting portion are heated to a molten state, and then, the connecting portion is folded, and the connecting portion and the bottom board are welded together, the production efficiency of the present invention is high, the automatic production is realized, and the product qualification rate is effectively improved.

A connector may couple to a non-cylindrical composite tubing having at least two lateral sides disposed in parallel and an open end. The connector may comprise first and second bonding plates adhered to an inner surface of the two lateral sides via an epoxy adhesive uniformly distributed. The first and second bonding plates may each have a distal lateral face defining a plurality of first threaded holes accessible at the open end of the composite tubing. The connector may also comprise an end plate having a plurality of first and second slotted holes disposed substantially in parallel and each aligned with an associating one of the first threaded holes. The connector may also comprise end plate fasteners loosely inserted through the first and second slotted holes and engaged with the first threaded holes. The end plate may also comprise one or more attachment points.

A method for use in efficiently joining together multiple workpieces to inhibit establishment of weld material in unwanted areas. The method uses a hybrid shaping-and-energizing system having a shaping tool and an ultrasonic horn. The method positions the hybrid shaping-and-energizing system proximate a workpiece, uses the shaping tool to form at least one recess in the proximate workpiece, and applies weld energy to the proximate workpiece using the ultrasonic horn. The recess is formed and the weld energy applied such that molten workpiece material becomes disposed within the recess, thereby inhibiting formation of weld material in the unwanted areas.

An automated edge band application machine has a board drive assembly and an opposed caster wheel that together capture and move a work piece edge into engagement with a rotating roller banding guide with edge banding captured between. An adhesive affixes the edge banding to the work piece responsive thereto. An edging detector is located along the path of the work piece edge, in a position in advance of the board drive assembly, and is configured to detect a presence of edge band on the edge of the work piece. When the edging detector detects edging, or at a precise distance along the edge band thereafter, a cutting die assembly severs the edge band. The board drive assembly automatically adjusts to varying thickness work pieces, engages with a work piece major surface, and rotates in synchrony with a drive spindle assembly and the rotating roller banding guide.

A connector for non-cylindrical composite tubing and methods for making the same. The method may involve assembling a connector for a non-cylindrical composite tubing by loosely fastening a pair of bonding plates to an end plate; arranging the bonding plates in an inward configuration; applying an epoxy adhesive onto the outer faces of the bonding plates, inserting the bonding plates into the open end of the composite tubing, inserting the bonding plate fasteners through the through-holes of the composite tubing and tightly fastening the bonding plate fasteners into the bonding plates until the bonding plates engage against the inner surface of the composite tubing until the epoxy adhesive is uniformly distributed. The method may also include steps of removing the bonding plate screw fasteners and adding shims between each bonding plate and the inner surface of the composite tubing in order to maintain a predetermined thickness of the epoxy adhesive.

A method or apparatus for joining a first component to a second component with an amalgamation plate includes heating the first component, the second component, the amalgamation plate, or combinations thereof, with either a joining tool or a heating element. The components are attached to the amalgamation plate with the joining tool, such that the first component, amalgamation plate, and the second component are fixedly attached to one another, and the amalgamation plate may be substantially surrounded by the first component and the second component, such that it is hidden from exposure. Portions of the amalgamation plate may be embedded into the components via rotation and/or linear force. A portion of the amalgamation plate may be recessed within the joining tool or an anvil before attaching the amalgamation plate to the either component.

An amalgamation plate for joining a first component to a second component has a planar body configured to be placed between the first component and the second component, and a plurality of first protrusions extending from a first side of the planar body. The first protrusions are radially dispersed from an axis of the planar body, and are configured to be embedded within either the first component and the second component. The amalgamation plate may also have a plurality of second protrusions extending from a second side, opposite the first side, of the planar body. The second protrusions are radially dispersed from the axis, and are configured to be embedded within the other of the first component and the second component via application of force substantially along the axis. The first protrusions and the second protrusions may be radially symmetric about the axis of the planar body.

Provided is a method for manufacturing a fishing net formed from a plastic net that can be handled by winding or folding although the net has plastic rigidity. The fishing net is manufactured by (1) a step of preparing a multifilament yarn formed by bundling a plurality of core-sheath type composite filaments, in each of which a core component is made of polyethylene terephthalate and a sheath component is made of polyolefin, (2) a step of preparing a yarn thread obtained by paralleling a plurality of the multifilament yarns, (3) a step of twisting or braiding four yarn threads 11, 12, 13, 14 to obtain a net constructed with strands 1 and intersections 2, (4) a step of heat-treating the net under without pressure to melt the sheath component of the yarn threads 11, 12, 13, 14 constituting the strands 1 and the intersections 2, followed by solidifying, thus obtaining a plastic net, and (5) a step of forming the fishing net using the plastic net.

The present disclosure encompasses three-dimensional articles comprising flexible-composite materials and methods of manufacturing said three-dimensional articles. More particularly, the present system relates to methods for manufacturing seamless three-dimensional-shaped articles usable for such finished products as airbags/inflatable structures, bags, shoes, and similar three-dimensional products. A preferred manufacturing process combines composite molding methods with specific precursor materials to form fiber-reinforced continuous shaped articles that are flexible and collapsible.
